Table 2
Iodine balances in 13 preterm infants during the first 27 days of life
| Mean iodine intake (μg/kg/day) | Mean iodine intake (μg/day) | Mean iodine urine output (μg/day) | Iodine balance (μg/day, +/−) | |
|---|---|---|---|---|
| Ranges are shown in parentheses. The iodine balance data (last column) were derived from the balances of the individual infants. It is NOT simply the difference between the mean intake (column 2) and mean output (column 3). | ||||
| Day 1 | 1.0 (0.6–1.7) | 0.92 (0.6–2.0) | 3.1 (1.3–7.8) | −2.19 (−0.4 to −2.8) |
| Day 6 | 3.6 (0.5–9.4) | 3.24 (0.6–8.2) | 5.5 (1.8–8.1) | −2.3 (−0.9 to −4.8) |
| Day 13 | 10.0 (1.5–33.4) | 10.0 (1.2–39.4) | 4.9 (1.6–13.6) | +5.5 (+35.4 to −1.1) |
| Day 27 | 19.6 (1.5–38.0) | 22.5 (1.5–49.6) | 17.2 (4.0–36.8) | +3.3 (+14.1 to −2.4) |
